It will be shown that the famous Dirac equation for the electron admits not only one local gauge invariance but two — and only two. As it is known, the first invariance (the ordinary phase invariance) corresponds to an electric charge ... (6.28) or (8.4) give the neutrino equations as a particular case, for g = 0, and g is quantized by the ... ................
